EXIF / JPEG metadata

Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

UKSTUG meeting (*with corrected links*) - Christian Haider: How values make systems simpler - 25 Sep 2024 @ 7pm BST
by UK Smalltalk Sept. 23, 2024

Sept. 23, 2024

Distinguishing between stateful Objects and Values has long been recognized as fruitful. Values are universal context-free abstractions that prevent side effects and allow for a functional programming style. Though programming languages provide simple Values like Integer and String, more complex Values are usually not supported. We show how to model complex structures as Values in Smalltalk, which allows for a simple and versatile implementation. The resulting Smalltalk systems are simple, clear and easily testable. Christian Haider [1] is the author of the PDFtalk library [2] used in smallCharts [3] and other projects. Underlying is a simple implementation of Values [4] which he uses extensively. Christian will show how Values make systems simpler and easier. Examples for some uses and the limits of the approach will be discussed. Since Values use only standard Smalltalk features, it can be used in most other Smalltalks. All of this code is available with MIT licence. This will be an online meeting from home. If you'd like to join us, please sign up in advance on: https://www.meetup.com/ukstug/events/302453141 [1] https://christianhaider.de/index_en.html [2] https://pdftalk.de/doku.php [3] https://smallcharts.de/english/ [4] https://pdftalk.de/doku.php?id=complexvalues

Pharo 12 and instanceVariables
by Herve Verjus Sept. 22, 2024

Sept. 22, 2024

Hi Everybody, I try to be up-to-date with Pharo trends and releases. In Pharo 12, we are switching to use fluid class declaration. Its' not easy to find stuffs illustrating fluid API. I have spend many hours to browse Pharo documentation, Github repos, slides, MOOcs, books, papers finding a way to clearly explain this "new way" of declaring a class. All Pharo introduction resources and Pharo 12 videos do not use fluid class declaration but the "old" way. I also use (and let's say teach) Pharo in my OOP lectures ð If I'm not wrong, the fluid class declaration does no more explicitly deal with instance (and class) variables. Instead, it deals now with slots, tags, shared variables, traits,...At a fist look, I was understanding that slots was a dynamic way to declare instance variables. After reading some pieces of paper, and if I'm not wrong , slots are not really instance variables and shared variables are not class variables. Avoiding the old class declaration, i.e. Â Â Â Â Â Object subclass #SomeClassName instanceVariableNames: 'instaVar1 instVar2 ...' ... is there a simple way to add an instance (or class) variable? Are instance variables gone in Pharo? I assume I missed something, but what? Many thanks. Cheers, Herve
